Oregon State Police are continuing to investigate a head-on crash south of Oregon City Tuesday that sent two people to the hospital.

Names and conditions of the victims are not available. One woman was taken by Life Flight helicopter to Legacy Emanuel Medical Center. The other was taken by ambulance to OHSU Hospital.

Lt. Gregg Hastings, OSP spokesman, said a 73-year-old woman was driving a Cadillac sport-utility vehicle towing a trailer north on Oregon 213 near South Greentree Drive around 11:30 a.m., when it crossed the center line. The SUV then crashed head-on with a southbound Chevrolet pickup driven by a 19-year-old woman.

After impact, the trailer became detached and stopped on the side of the highway.
